I have researched the reviews online and basically they said that both the Takumars were not very good. The Pentax 50mm had pretty good reviews. The camera is what it is. All this equipment is in pristine condition and is in the hands of my daughter. I was wondering if anyone had real world experience with any of this equipment, especially the lenses, that could confirm or refute the online reviews. In other words, are any of these lenses any good? TIA for any help.
